The presence of undesired vegetation causes substantial damage to useful crops, especially agricultural products that satisfy man's basic food needs, such as soybeans, barley, wheat, and the like. The current population explosion and concomitant world food shortage demand improvements in the efficiency of producing these crops. Prevention or minimizing the loss of a portion of valuable crops by killing, or inhibiting the growth of undesired vegetation is one way of improving this efficiency.

A wide variety of materials useful for killing, or inhibiting (controlling) the growth of undesired vegetation is available; such materials are commonly referred to as herbicides. The need exists, however, for still more effective herbicides that destroy or retard weeds without causing significant damage to useful crops.

SYNTHESIS

As shown in Equation 1, the compounds of Formula I, wherein R=SCH(R₂)A or R=SO₂ CH(R₂)A, can be prepared by reacting an appropriately substituted sulfonyl isocyanate of Formula II with an appropriate 2-aminopyrimidine or 2-amino-1,3,5-triazine of Formula III, R, R₁, X, Y and Z being as defined above. ##STR24##

The reaction is best carried out in inert aprotic organic solvents such as methylene chloride, tetrahydrofuran or acetonitrile, at ambient pressure and temperature. The mode of addition is not critical; however, it is often convenient to add the sulfonyl isocyanate to a stirred suspension of amine III. Since such isocyanates are usually liquids, their addition can be easily controlled.

The reaction is generally exothermic. In some cases, the desired product is insoluble in the warm reaction medium and crystallizes from it in pure form. Products soluble in the reaction medium are isolated by evaporation of the solvent, trituration of the solid residue with solvents such as 1-chlorobutane or ethyl ether, and filtration.

The intermediate sulfonyl isocyanates of Formula II wherein n≠1 can be prepared as shown in Equation 2 by reacting the corresponding sulfonamides of Formula IV with phosgene in the presence of n-butyl isocyanate at reflux in a solvent such as xylene, according to the procedure of H. Ulrich and A. A. Y. Sayigh, Newer Methods of Preparative Organic Chemistry, Vol. VI, p. 223-241, Academic Press, New York and London, W. Foerst Ed. Alternatively, the reaction described in Equation 2 can be carried out in the presence of a catalytic amount of a tertiary organic amine, such as 1,4-diaza[2.2.2]bicyclooctane.

In cases where formation of the desired sulfonyl isocyanate is difficult by the above procedure, the sulfonylurea formed by the reaction of butyl isocyanate with the appropriate sulfonamide is treated with phosgene according to the above reference. ##STR25##

Compounds of Formula I may also be prepared from the sulfonamides of Formula IV and heterocyclic carbamates of Formula V as outlined in Equation 3. Treatment of IV with trimethylaluminum, followed by the addition of V will give compounds of Formula I after aqueous acidic workup. The carbamates of Formula V are readily prepared from the appropriate aminopyrimidine or aminotriazine by procedures well known in the art. ##STR26##

As shown in Equation 4, the compounds of Formula I can be prepared from the appropriate sulfonamides of Formula IV and heterocyclic amines of Formula III via the intermediate sulfonyl carbamates of Formula VI. Heating equimolar amounts of VI and III in a high boiling solvent, for example dioxane, will yield compounds of Formula I. ##STR27##

The sulfonamides of Formula IV can be prepared by a variety of procedures reported in the literature. As shown in Equation 5, the thioether of Formula VII may be prepared from the appropriate 2-aminothiophenol and an alkyl halide as described in the literature, e.g. R. N. Prasad, et al. Can. J. Chem. 44, 1247 (1966). The formation of the benzenesulfonyl chloride and the corresponding sulfonamide IVa has been previously described (co-pending application U.S. Ser. No. 192,034, filed Sept. 29, 1980). The oxidation of IVa to the corresponding 2-alkylsulfinyl or 2-alkylsulfonylbenzenesulfonamides of Formula IVb may be carried out utilizing a variety of standard literature procedures, including m-chloroperoxybenzoic acid (C. R. Johnson, et al., Tetrahedron 25, 5649 (1969)), or with aqueous hydrogen peroxide in acetic acid (F. G. Bordwell, et al., J. Amer. Chem. Soc. 77, 1141 (1955)). ##STR28##

In some cases, diazotization of VII procedures more smoothly if oxidation is carried out first. As shown in Equation 6, protection of the amino group, for example as the acid amide, followed by oxidation, deprotection and then diazotization produces sulfonamide IVb. ##STR29##

Compounds of Formula IV wherein n≠1 may also be prepared from 2-halonitrobenzenes of Formula VIII as outlined in Equation 7. Halide displacement in VIII by thiols (n=0) or sulfinates (n=2) is widely reported in the literature (for general reviews see, "Organic Chemistry of Sulfur", S. Oae, ed., Plenum Press, New York, 1977, pp. 232-233; Reid, "Organic Chemistry of Bivalent Sulfur," Chemical Publishing Co., New York, Vol. 2, pp. 16-21, 24-29; Vol. 3, pp. 11-14; Peach, in Patai, "The Chemistry of the Thiol Group," pt. 2, pp. 735-744, John Wiley and Sons, Inc., New York, 1974). ##STR30##

Compounds of Formula IX where n≠1 may also be prepared as shown in Equation 8 [in addition to references cited above, see, Zh Obshch. Khim, 35, (8) 1361 (1965) and J. Chem. Soc., 763 (1946)]. Reduction of IX to the amine X can be carried out by a variety of standard literature procedures, including catalytic hydrogenation (Rylander, "Catalytic Hydrogenation over Platinum Metals," pp. 168-202, Academic Press, Inc., New York, 1967) and reduction with iron (D. Cowsley et al., Synthesis 118 (1977)) or stannous chloride (Org. Synth., Coll. Vol. 2, 130 (1943); ibid, 3, 240, 453 (1955)) in acidic medium. Compounds of Formula IX wherein n=0 may also be oxidized to the corresponding sulfones prior to reduction. ##STR31##

Ortho-lithiation of appropriately substituted benzene derivatives also provides a route to sulfonamides of Formula IV. As shown in Equation 9, the N-t-butylbenzenesulfonamides of Formula XI may be ortholithiated [for general review, see H. W. Gschwend et al., Organic Reactions, 26, 1 (1979)] and then trapped with sulfur, followed by alkyl halide, or disulfide to give sulfonamides of Formula IVa [S. Gronowitz et al., Acta, Chem. Scand. 21, 812 (1967) and Chem. Ber., 99, 3215 (1966)]. Treatment of XII with sulfur dioxide, followed by alkyl halide will give sulfonamides of Formula IVb [JACS, 74, 5177 (1952)]. ##STR32##

The lithium sulfonates of Formula XIII can also be ortholithiated to give compounds of Formula XIV as shown in Equation 10. Treatment of XIV with sulfur electrophiles as in Equation 9 will give the sulfonates of Formula XV [for example, see J. C. Martin et al., JOC, 45, 3728 (1980)]. Conversion of XV to the sulfonamides of Formula IV can be accomplished using thionyl chloride and a catalytic amount of dimethylformamide and then treating the sulfonyl chloride with ammonia. ##STR33##

Sulfonamides of Formula IV may also be prepared from chlorosulfonamides of Formula XVI (see U.S. Pat. No. 4,127,405 and U.S. Pat. No. 4,169,719 for preparation of XVI) and the appropriate mercaptan of Formula XVII as shown in Equation 11. Heating XVI and XVII in a high boiling solvent, for example dimethylformamide, in the presence of two equivalents of base will give IVa after acidic workup. Oxidation of IVa will yield sulfonamides of Formula IVb. ##STR34##

Compounds of Formula I may also be prepared by the reaction of the substituted sulfonamides of Formula IV with an appropriate heterocyclic isocyanate as previously described (co-pending applications U.S. Ser. No. 098,725 and U.S. Ser. No. 098,722, filed Nov. 30, 1979).

Compounds of Formula Ib, where R=SOCH(R₂)A can be prepared from the appropriate compounds of Formula Ia wherein R=SCH(R₂)A by oxidation with m-chloroperoxybenzoic acid as shown in Equation 12. The reaction can be carried out by stirring equivalent amounts of Ia with m-chloroperoxybenzoic acid (MCPBA) in an inert solvent such as chloroform at 0° to reflux for 12-24 hours. The insoluble m-chlorobenzoic acid produced is removed by filtration and the chloroform solution is concentrated to yield the crude product. Purification by standard techniques will give the desired product. Oxidation of Ia with one equivalent of hydrogen peroxide in acetic acid at room temperature will also give the sulfoxides Ib. ##STR35##

Compounds of Formula I wherein A represents a hydroxyalkyl group are most readily prepared from the corresponding protected alcohols. For example, treatment of Ic with dilute acid will yield the hydroxyethyl compounds of Formula Id as shown in Equation 13. The choice of alcohol protecting group need not be limited to the tetrahydropyranyl group, as would be readily apparent to one skilled in the art. The compounds of Formula Ic may be prepared by methods taught in Equations 1-12. ##STR36##

The synthesis of heterocyclic amine derivatives has been reviewed in "The Chemistry of Heterocyclic Compounds," a series published by Interscience Publ., New York and London. 2-Aminopyrimidines are described by D. J. Brown in "The Pyrimidines", Vol. XVI of the above series. 2-Amino-1,3,5-triazines can be synthesized according to the methods described by E. M. Smolin and L. Rapaport in "s-Triazines and Derivatives," Vol. XIII of the same series.

Agriculturally suitable salts of compounds of Formula I are also useful herbicides and can be prepared in a number of ways known to the art. For example, metal salts can be made by contacting compounds of Formula I with a solution of an alkali or alkaline earth metal salt having a sufficiently basic anion (e.g., hydroxide, alkoxide, carbonate or hydroxide). Quaternary amine salts can be made by similar techniques.

Salts of compounds of Formula I can also be prepared by exchange of one cation for another. Cationic exchange can be effected by direct contact of an aqueous solution of a salt of a compound of Formula I (e.g., alkali or quaternary amine salt) with a solution containing the cation to be exchanged. This method is most effective when the desired salt containing the exchanged cation is insoluble in water and can be separated by filtration.

Exchange may also be effected by passing an aqueous solution of a salt of a compound of Formula I (e.g., an alkali metal or quaternary amine salt) through a column packed with a cation exchange resin containing the cation to be exchanged for that of the original salt and the desired product is eluted from the column. This method is particularly useful when the desired salt is water-soluble.

Acid addition salts, useful in this invention, can be obtained by reacting a compound of Formula I with a suitable acid, e.g., p-toluenesulfonic acid, trichloroacetic acid or the like.

The compounds of this invention and their preparation are further illustrated by the following examples wherein temperatures are given in degrees centigrade and parts are by weight unless otherwise designated.

FORMULATIONS

Useful formulations of the compounds of Formula I can be prepared in conventional ways. They include dusts, granules, pellets, solutions, suspensions, emulsions, wettable powders, emulsifiable concentrates and the like. Many of these may be applied directly. Sprayable formulations can be extended in suitable media and used at spray volumes of from a few liters to several hundred liters per hectare. High strength compositions are primarily used as intermediates for further formulation. The formulations, broadly, contain about 0.1% to 99% by weight of active ingredient(s) and at least one of (a) about 0.1% to 20% surfactant(s) and (b) about 1% to 99.9% solid or liquid diluent(s). More specifically, they will contain these ingredients in the following approximate proportions:

Lower or higher levels of active ingredient can, of course, be present depending on the intended use and the physical properties of the compound. Higher ratios of surfactant to active ingredient are sometimes desirable, and are achieved by incorporation into the formulation or by tank mixing.

Typical solid diluents are described in Watkins, et al., "Handbook of Insecticide Dust Diluents and Carriers", 2nd Ed., Dorland Books, Caldwell, N.J., but other solids, either mined or manufactured, may be used. The more absorptive diluents are preferred for wettable powders and the denser ones for dusts. Typical liquid diluents and solvents are described in Marsden, "Solvents Guide," 2nd Ed., Interscience, New York, 1950. Solubility under 0.1% is preferred for suspension concentrates; solution concentrates are preferably stable against phase separation at 0° C. "McCutcheon's Detergents and Emulsifiers Annual", MC Publishing Corp., Ridgewood, N.J., as well as Sisely and Wood, "Encyclopedia of Surface Active Agents", Chemical Publishing Co., Inc., New York, 1964, list surfactants and recommended uses. All formulations can contain minor amounts of additives to reduce foaming, caking, corrosion, microbiological growth, etc.

The methods of making such compositions are well known. Solutions are prepared by simply mixing the ingredients. Fine solid compositions are made by blending and, usually, grinding as in a hammer or fluid energy mill. Suspensions are prepared by wet milling (see, for example, Littler, U.S. Pat. No. 3,060,084). Granules and pellets may be made by spraying the active material upon preformed granular carriers or by agglomeration techniques. See J. E. Browning, "Agglomeration", Chemical Engineering, Dec. 4, 1967, pp. 147ff. and "Perry's Chemical Engineer's Handbook", 5th Ed., McGraw-Hill, New York, 1973, pp. 8-57ff.

UTILITY

The compounds of the present invention are active herbicides. They have utility for broad-spectrum pre- and/or post-emergence weed control in areas where complete control of all vegetation is desired, such as around fuel storage tanks, ammunition depots, industrial storage areas, parking lots, drive-in theaters, around billboards, highway and railroad structures. Alternatively, the subject compounds are useful for the selective pre- or post-emergence weed control in crops, such as wheat and soybeans.

The rates of application for the compounds of the invention are determined by a number of factors, including their use as selective or general herbicides, the crop species involved, the types of weeds to be controlled, weather and climate, formulations selected, mode of application, amount of foliage present, etc. In general terms, the subject compounds should be applied at levels of around 0.05 to 10 kg/ha, the lower rates being suggested for use on lighter soils and/or those having a low organic matter content, for selective weed control or for situations where only short-term persistence is required.

The compounds of the invention may be used in combination with many other commercial herbicide examples of which are those of the triazine, triazole, uracil, urea, amide, diphenylether, carbamate and bipyridylium types.

The herbicidal properties of the subject compounds were discovered in a number of greenhouse tests. The test procedures and results follow.

TEST A

Seeds of crabgrass (Digitaria sp.), barnyardgrass (Echinochloa crusgalli), wild oats (Avena fatua), cassia (Cassia tora), morningglory (Ipomoea sp.), cocklebur (Xanthium sp.), sorghum, corn, soybean, rice, wheat and nutsedge tubers (Cyperus rotundus) were planted in a growth medium and treated pre-emergence with the chemicals dissolved in a non-phytotoxic solvent. At the same time, cotton having five leaves (including cotyledonary ones), bush beans with the third trifoliolate leaf expanding, crabgrass, barnyardgrass and wild oats with two leaves, cassia with three leaves (including cotyledonary ones), morningglory and cocklebur with four leaves (including the cotyledonary ones), sorghum and corn with four leaves, soybean with two cotyledonary leaves, rice with three leaves, wheat with one leaf, and nutsedge with three to five leaves were sprayed. Treated plants and controls were maintained in a greenhouse for sixteen days, whereupon all species were compared to controls and visually rated for response to treatment. The ratings are based on a numerical scale extending from 0=no injury, to 10=complete kill. The accompanying descriptive symbols have the following meanings:

B=burn;

C=chlorosis and/or necrosis;

D=defoliation;

E=emergence inhibition;

G=growth retardation;

H=formative effects;

S=albinism;

U=unusual pigmentation;

X=axillary stimulation; and

6Y=abscised buds or flowers.

The ratings for the compounds tested by this procedure are presented in Table A. It will be seen that certain of the compounds tested are highly active herbicides and that several have potential utility for weed control in crops such as wheat and soybeans. ##STR141##

TEST B

Two plastic bulb pans were filled with fertilized and limed Fallsington silt loam soil. One pan was planted with corn, sorghum, Kentucky bluegrass and several grassy weeds. The other pan was planted with cotton, soybeans, purple nutsedge (Cyperus rotundus), and several broadleaf weeds. The following grassy and broadleaf weeds were planted: crabgrass (Digitaria sanguinalis), barnyardgrass (Echinochloa crusgalli), wild oats (Avena fatua), johnsongrass (Sorghum halepense), dallisgrass (Paspalum dilatatum), giant foxtail (Setaria faberii), cheatgrass (Bromus secalinus), mustard (Brassica arvensis), cocklebur (Xanthium pensylvanicum), pigweed (Amaranthus retroflexus), morningglory (Ipomoea hederacea), cassia (Cassia tora), teaweed (Sida spinosa), velvetleaf (Abutilon theophrasti), and jimsonweed (Datura stramonium). A 12.5 cm diameter plastic pot was also filled with prepared soil and planted with rice and wheat. Another 12.5 cm pot was planted with sugar beets. The above four containers were treated pre-emergence with several test compounds within the scope of the invention.

Twenty-eight days after treatment, the plants were evaluated and visually rated for response to the chemical treatments utilizing the rating system described previously for Test A. The data are summarized in Table B. Note that certain compounds have high pre-emergence activity.

TEST C

The test chemical, dissolved in a non-phytotoxic solvent, was applied as an overall spray to the foliage and surrounding soil of selected plant species. One day after treatment, plants were observed for rapid burn injury. Approximately fourteen days after treatment, all species were visually compared to untreated controls and rated for response to treatment. The rating system was as described previously for Test A. The data are presented in Table C.

All plant species were seeded in Woodstown sandy loam soil and grown in a greenhouse. The following species were grown in soil contained in plastic pots (25 cm diameter by 13 cm deep): soybeans, cotton, alfalfa, corn, rice, wheat, sorghum, velvetleaf (Abutilon theophrasti), sesbania (Sesbania exaltata), Cassia (Cassia tora), morningglory (Ipomoea hederacea), jimsonweed (Datura stramonium), cocklebur (Xanthium pensylvanicum), crabgrass (Digitaria sp.), nutsedge (Cyperus rotundus), barnyardgrass (Echinochloa crusgalli), giant foxtail (Setaria faberii) and wild oats (Avena fatua). The following species were grown in soil in a paper cup (12 cm diameter by 13 cm deep): sunflower, sugar beets, and mustard. All plants were sprayed approximately 14 days after planting.

The results of this study indicate that the test compound has utility for post-emergence weed control in wheat.
